Original application filed April 10, 1919, Serial NO. 288,95 L' Divided and this application filed October 20,

1920. Serial No. 418,178.

To all whom it may concern:

Be it known that 1, JOHN H. RIOHARD- SON, a citizen of the United States, residing at lVakefield, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Sewing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to sewing machines and more particularly to work supporting horns for McKay shoe sewing machines.

The object of the invention is to provide a work supporting horn having novel and improved heating means, which is particularly adapted for use on McKay shoe sewing machines.

With this object in view the features of the invention consist in certain constructions, arrangements and combinations of parts hereinafter described, and claimed, the

advantages of which will be obvious to those skilled in the art.

The several features of the invention will be clearly understood from the following description and accompanying drawings in which:

Figure 1 is a side elevation of a portion of the frame of a McKay shoe sewing machine with a work supporting horn applied thereto embodying the features in their preferred form; Fig. 2 is a detail sectional View of the horn taken on the line 2-2 of Fig.1, and Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1.

In the drawings a work supporting horn 2 is shown applied to a portion of the frame 4 of a McKay shoe sewing machine, which machine may be and preferably is the same as the one illustrated and described in Patent Number 1,4:12A23 issued April 11, 1922, on applicants co-pending application, Serial No. 288,954, filed April 10, 1919, of which the present application is a division and to which reference may be had for a full and complete description of the same.

In the construction shown, a hot water heating device is employed for heating the work supporting horn 2 whereby hot water is caused to circulate from the base of the horn up to a point in proximity to the tip of the horn and then backv to the base. The horn is provided with the usual spindle 6 mounted to rotate in an aperture in a bracket 8 secured to the machine frame. The horn is further provided with a cylindrical base 10 and an upwardly curved portion 12 in the upper end of which is mounted the usual whirl. or looping device 14. This device is driven through the usual arrangement of shafts andv gears 16 extending through the upwardly curved portion 12 and the base 10. The upper portion of the base 10 is cored out to form a water container 17 below which is an annular recess 18, a flange on the base forming the outer wall of the recess and the spindle 6 forming the inner wall. An annular steam chamber 20 is located in the recess 18 andsubstantially fills said recess. The upwardly extending curved portion 12 of the horn is cored out to form an inverted U-shaped water container or passage 22 which extends from a point in proximity to the base to the upper portion of the horn. The lower ends of the passage are connected with the water container 17 by tubular conduits 2 1. The lower end of one of the conduits is closer to the top of the water container 17 than the other conduit, so that when the container is heated, the water therein and in the passage 22 is caused to' circulate and thereby uniformly heat the horn to properly condition the waxed thread which extends through the horn. lVater is supplied to the passage 22 and the water container 17, through an opening leading into the upper end of the passage, which opening is normally closed by a removable plug 26 threaded therein.

The nature and scope of the invention having been indicated, and a machine cub bodying the several features of the invention having-been specifically described, What is claimed is 1. A rotatable shoe supporting horn for shoe sewing machines of the class described having, in combination, a base, an upwardly curved portion extendingtherefrom toenter the shoe, a supporting spindle extending downwardly therefrom, a water reservoir located in saidbase, said upwardly curved portion having a water passage formed therein having inlet and outlet openings connected with the reservoir and so ar ranged that when the reservoir and passage is filled with water and the water in the reservoir isv heated, it will be caused to ci-rculate through the passage and reservoir.

2. A rotatable shoe supporting horn for shoesewing machines of the class described having, in combination, a base having a Water reservoir located therein, a. supporting spindle extending downwardly therefrom, an upwardly curved portion to enter the shoe and having a water passage formed therein connected with the reservoir, and means for heating the reservoir.

3". A rotatable shoe supporting hernfor shoe sewing machines of the class described having, in combina-tion, base ha'vinga Water reservoir located therein, a supporting spindle extending downwardly therefrom, an, upwardly curved portion to enter the shoe and having a U-shaped, water passage formed therein extending through a portion thereof and connected by two conduit-swith the reservoir, the lower ends of said conduits being located at different distances from the bottom of the reservoir, and means for heating the reservoir.

4. A rotatable shoe supporting horn for shoe sewing machines of the class described having, in combination, a base having a water reservoir located in the upper portion thereof, and having an annular recess located below the reservoir, a steam chamber lo.- cated in said recess, a supporting spindle extending downwardly from the. base, and an upwardly curved portion to enter the shoe having a hollowed out portion connected with the water reservoir.
